No.
I emailed them around 4pm when I got home yesterday right when I noticed it yet, which is 7pm in Brooklyn, I beleive. When I first emailed them about having won the auction it was a Friday morning and they didn't hit me back until Monday afternoon... so I'm guessing it will take them a while. If I don't hear back by the end of the day, I'm calling them up.
They better not do something like "We'll send it out as soon as you send us the wrong one back," because that would be annoying as hell. I'm a college student, I'd shoot an AR or FAL otherwise... or DPMS Panther...

UPDATE:
I called them just now and they seemed very apologetic. He said he'd send out a new one as soon as possible and I should send back the incorrect one when I can... which will be Friday, my payday, at soonest...
